Boulder County Public Health reported Tuesday that four more people had died from complications due to the new coronavirus since Monday afternoon, bringing the death toll 15.

Chana Goussetis, spokesperson for the Boulder County Public Health department, said of the 15 who died, 12 of those were either a staff member or resident at Boulder County long-term care facilities. Goussetis said further information about the people whose deaths were reported Monday and Tuesday was not available, including their age, gender, or health condition before contracting the virus.

In Boulder County, there are 290 people who have tested positive or whose cases are considered probable, according to the Boulder County Public Health department Tuesday afternoon. Of those 290, 36 cases are under investigation by epidemiologists, 79 people have been hospitalized due to the virus, and 117 have recovered from the disease.

The average age of Boulder County residents who have tested positive for the disease, or whose cases are considered probable, is 51. However the ages of those infected ranges widely, from infants up to at least 98. There are three cases reported among residents younger than 9, including an infant; five among residents between ages 10 and 19 and 59 among residents between ages 20 to 29. The Boulder County Coroner detailed April 9 that among the deaths were several people who had been in their 90s, including a 98-year-old woman who died April 4.

The Colorado Department of Health and Environment reported that state data, through Monday afternoon, shows that there have been 329 deaths due to complications from the coronavirus. There are 7,941 coronavirus cases; 1,556 people hospitalized; and 78 outbreaks at residential and non-hospital health facilities. More than 39,500 people have been tested for the disease.

Public health officials have said that the number of cases reported is likely not a full reflection of the total infected, due to limited testing and pending test results.

Reflecting on Boulder County’s numbers, Goussetis said it would be “difficult to make make conclusions based on the illness and recovery data” since it is a reflection of only those who have tested positive or whose cases are probable.

“We are cautiously optimistic that the social distancing is working, but emphasize that we must all keep it up a bit longer,” she said. “We are preparing to respond to hospital surge if it is needed in the future, but as of today, there is no need for surge capacity.”

Gov. Jared Polis issued a statewide stay-at-home order March 25, mandating residents leave their homes only for essentials like grocery shopping and caring for loved ones. On April 6, the governor extended the stay-at-home order to last through April 26. Continuing to follow this order will help to fight the spread of the disease, Goussetis said.

“It may not feel like you’re doing anything, but staying home is the number one thing you can do to keep yourself and loved ones safe, and to be most helpful to public health and first responders,” she said. “By minimizing the chance that you may come in contact with someone who is ill, you’re keeping others safe, and helping to ensure limited resources are used appropriately.”
